For those who don't know the full story, here is the scoop: Enrique Peña Nieto, the Institutional Revolutionary Party (PRI) candidate, won the presidential election with just 38.2% of the popular vote while challenger Andrés Manuel López Obrador got 31.6% of the vote. The PRI ruled Mexico from 1929-2000, and had a culture of corruption and repression that still lingers with Mexicans. López Obrador has filed a suit to void the results. There are charges of voter corruption and purchase of votes, including the distribution of Soriana supermarket gift cards.

Both Mr. Peña Nieto and the main grocery chain involved in the allegations, Organización Soriana SAB, have denied any wrongdoing. "We maintain that there was no buying of votes and that the election was completely fair," said a Mr. Peña Nieto spokesman. "We also reiterate that financing was conducted in a transparent manner and done in accordance with the law."
